Hi ryan83,
You can read a little more about the different types and blends of latex in post #6 here and more about 100% natural vs blended Talalay in post #2 here.
While a sample won’t tell you much if anything about how a particular mattress will feel when you sleep on it … most people would notice a difference between the different types and blends of latex and different firmness levels if that’s what you mean.
